VHP Decontamination Lock

VHP Decontamination Lock

Material airlock providing rapid H2O2 decontamination

Decontamination locks are most frequently used as a pass-through to transfer material between rooms with different classes of cleanliness (typically B and C), whereas material must be decontaminated (by means of surface sterilization) before entry into the room. Loaded materials are decontaminated using hydrogen peroxide vapour with a 6-log reduction. A hydrogen peroxide vapour generator is a part of the equipment.

Description

  • Integrated VHP generator
  • Decontamination pass-through cabin may be fitted onto the wall separating individual rooms
  • Lock complies with the leak tightness classes pursuant to ISO 10648-2
  • “B” class cleanliness according to the EU GMP Standard
  • Electronic control system for automatic adjustment of basic operating modes managed by Siemens PLC
  • Color touchscreen controls
  • Mobile perforated shelves allow sterilization of the product from all sides
  • Process works at normal temperatures (at about 25 to 30 °C) and normal pressures
  • Jacket material – stainless steel AISI 304
  • Pass-through chamber material – AISI 316L with a thickness of 3.00 mm, polished surface finish, Ra < 0.6 µm
  • Rounded corners R = 55 mm
  • Inlet and outlet H14 HEPA filtration
  • Possible validation of decontamination cycle
  • Possible data recording on a recording unit, printer or PC
  • Low operating costs
  • Decontamination a low-temperature

Standards and Options

Standards

Chamber closing door

It is made of PMMA with a thickness of 25 mm. The door is sealed using a pneumatic seal made of silicon. The closing of the door is monitored by a sensor; another sensor monitors the mechanism which prevents the door from being opened.

VHP distribution

Distribution pipe for optimal gassing inside the chamber

Perforated shelves

4 pcs of standard perforated shelves for loaded material

Safety Features

Pressure fuse

Options

  • H2O2 concentration sensor – high – process sensor inside the chamber
  • H2O2 concentration sensor – low – safety sensor inside the chamber
  • H2O2 concentration sensor – low – safety sensor outside the chamber
